vMy inventionlis an impr lating machines.'

It has for its o invention is a machine that-will be able to adda-nd subtract numbers' placed upon a sheet of paper whether in vertical, that is columnar, or in horizontal, that1s linear,

arrangement, or in both.- vAnotherpart of myinvention is the construction of a machine that will be able to calculate'simultaneously, the totals of various `columns of numbers and will simultaneously calculate the grand total of said totals. i

The invention is illustrate ings forming part of the application. Of such drawings Figure 1 shows a front elevation of the calculating machine and of a portion of the typewriter whereonv it is i mounted. The covers are shown so as to give a picture of the parts as viewed by thev operator.

Fig. 2 is another elevation of the same parts and differs from Fig. 1 principally in the fact that the covers have been removed. It does not show all of the parts as that would be unnecessary.

F ig. 3 is a plan of the top of the actuator and immediately beneath the totalizer. i

Figs. 4 and 5 are front elevations show ing some of the parts in their various operating positions. Y y

Fig. 6 is an end elevation taken along the plane 6 6 of F ig. 1. Similarly Figs. T and 8 are respectively taken along the planes 7-7 and 8 8 of `Fig. 1. A

For-1 the understandin of this invention it is. suiiicient to recall t at in the machineas at present on the market, there is mountedlupon the framing-1, of the typewriter," an. actuator 2,'which is Fconnected by means off links 3.to ,the numeral key levers 100 of thetypewriter.` The depressing` of any ofv the key. levers and consequent operating of thisconnectingflink 3, results, by a mecha--l nism .described .1in said patent, in thev'vibratingfLOf-a digit shaft 4,'to an amount dependent upon-and corresponding to the valueof'the numeral key depressed' Thedepressing of any of the key'levers 100 results also in the operating of a universal rock shaft, 5. y By the coperation of the digit shaft 4,7and the rocktshaft 5, there isgiven to the sector 6, which is mounted. thereon, a movement about to be described. The sector 6 is mounted upon the digit shaftl 4 so las to rotate therewith, but is also able to swing about an axis which is perpendicular to the axis of the shaft 4. Normally the sector 6 stands in an inclined non-operating position as shown in the figures. By the operation of the rock shaft 5 the Vsector is first brought into an active position with its plane perpendicular to the axis of the. digit shaft 4, and is then given its move-4 ment, after the completion of which itis again brought to its nonactive position. During the return of the parts to their normal positions the sector occupies its non- A active position and thus does not reverse the action that it produced during its vibrating in its forward movement. l

The rock shaft 5, the digit shaft 4, the master dog 15 and other parts of my present machine may be variously constructed and connected as far as my present invention is concerned. Suitable mechanism coperating with these parts is shown in my Patent No. 893,? 19 hereinbefore referred to; also in a later patent of mine No. 1,148,732 dated August 3, 1915, more refined mechanism is shown, and suitable mechanism is'shown in other patents. In short, this part of the Tabl calculating machine is well known in the art.

Coperating with the sector 6 in its active position are a direct gear 7 and a reverse gear S. The three gears, namely the sector'v 6, the direct gear 7 and the reverse gear 8, rotate about parallel axes. The direct gear .Y 7 and the reverse gear 8 are always in mesh with each other. To produce addition the direct 'gear 7 is located in a place where the sector 6 will mesh therein during it-s advance or operating stroke. The reverse gear 8 is withdrawn to prevent interference.v To produce subtraction it is the reverse gear 8 that is'placed in mesh with the sector and the direct gear 7 that is withdrawn to prevent interference. This is accomplished by providing both the direct gear and the reverse gear with a lever 9, which cooperates with agroove in each one of them. The lever 9 is fulcrumed at 10 in the framing of the machine.. The reverse gear 8 is provided with a long shaft 11, which extends to the left'and at'its extreme end coperates with the helic'ally shaped cam slot, 12. The latter is operated by a handle 13, which forms one piece with the cam. By the proper locating of said handle 13, it is evident that either the direct gear or the reverse gear may be jplaeed in a position to coperate with the sector 6, during its operating stroke asmay be desired.

Splined upon the shaft whereon the direct gear 7 is mounted is the master gear 14. The direct gear 7 and the master gear 14 thereforealways rotate an equal amount in the same-direction. Coperating with the mastergear 14 is a master dog 15. The latter is .moved 'through the proper intermediate mechanism which is operated by the rock shaft 5.

The master gear and master dog may cooperate with the totalizer gea-rs and totalizer chain disconnectors, as described in said Patent No. 893,719 or in my Patent No. 893,718, dated July 21, 1908. The totalizer shown in the drawings, however, has the outline of the totalizers that were being manufactured for the market at the time when the present application was filed and the con struction of which can be understood from the patent to Goldberg 1,099,497, dated June 9, 1914. Said Goldberg patent also describes certain mechanism for computing numbers not written in the decimal system but those features of said patent are not shown in the vpresent case. The totalizer base 16, is

-mounted upon the totalizer bar 17. The latter is supported in the framework of the machine and connected to the carriage 18, ofthe typewriter, so as to move in unison therewith. The totalizer gears and totalizer disconnectors are therefore carried .Seriate/1i through the master gear and master dog.v during the operation of the machine. All th'e above mechanism is old.

To accomplish the results desired it was decided to be advisable to practically reproduce 'and place on the side another master couple, that is another master gear and `another master dog, to cooperate with another totalizer. Moreover for convenience the latter'totalizer has been made stationary and not movable as with the totalizers coperating with the master gear 14 To offset'the stationariness of the Vside totalizen 19, its cooperating master gear vand master dog were made movable relatively thereto. In order toV distinguish-clearly the master gear and master dog, which cooperate with the stationary totalizer, from the master gear and master dog which coperate with the totalizers mounted upon the totalizer bar and which travel iny unison with the carriage of the typewriter, lthel :former will be `called universal and the latter columnar. The side totalizen'the side 'master gear 'and the'side master d og will therefore be the universal totalizer, universal master gearand the universal'fmaster dog. The others will be the columnar totalizer, the columnar mastergear and the columnanm'aster dog. VThe reason why the word universal has been-adopted for the side totalizer is because it will be evident from Vthe further description that it may be used universally, that is with numbers located on any portion Aof the paper. Furthenbecause of the construction of this machine, ,it can be used to obtain the total of numbers located on the paper in column determined bythe position of the totaliz'er 'upon1 said totalizer bar.

There will now be described the mechanism'b'yfmeaisof which the universal master ear obtains its movement.

T e 'directf gear 7 is in mesh with an auxiliary gear 20, which is rotatably mounted upon a stud 21 fastened in the framing (Figs. 2, 4 'and 5). The auxiliarygear 2O thereforealways rotates in a direct-ion dependent upon the rotation of the direct gear 7. Both vrotatably and slidably mounted in the frameworkv of the machine is a shaft 22 which ends at its eXtreme left in a 'stud 23 whereby it is laterally located, and a gear 24 rigidly fastened thereto. Somewhat to the right is another'gear 25 also rigidly fastened thereto. Still farther to the right and at its extreme right portion is a long pinion, 26. The gear 24 is located i'n the immediate vicinity ofthe auxiliary gear 20 and the shaft 22 when brought to a lateral position to mesh said gear 24 and the auxiliary gear 20, will be given a rotation in the same direction as the rotation of the master gear 14. l1`he gear 25 is ylocated in the vicinity of the master gear 14 and when properly laterally located to mesh therewith, the shaft 22 will be given a rotation in the 4opposite direction as said master gear. Said 'shaft 22 is capable of being located in any of three lateral positions which I shall denominate, 1, a similar position, 2, a reverse position, and 3, a nonactive position. To bring it to any of said positions the gear 25 rigidly fastened to the shaft 22 is provided with a hub which has therein "a groove 27 wherein is embraced a roller 28 mounted at the end of one arm -of alever, 29another arm of which is provided with a.spring.30.V The lever is fulcrumed in thepframework at, 31. The vlever 29 is also providedwith a .roller 32. fin examination ofdthendrawing.willshowvthat the tension offthegspringtends constantly to raise the rolleri 32.upward,r andshift the shaft 22 to th8.1ftfif the tensionf of-thcspring would began;lresisted.;themthej shaft would' be lgzbropghttodtsextremeposition to the left, in .saldposition the gear would be in mesh Wi1hthe-master Igear 14.

This down- 3. i ;,ward `pullis resisted by reason of vsaid handlefengaging Ea' ratchet rod 36. Then said handleel-iis-.moved from its extreme left positionto another position to the right, it pushes-theshaft 22 alongftherewith, hut 4Qritselffncapableof being pushed bach to its priorgposition on :account of the ratchetJv shape-.,fllthe 1od36.The shaft 22 may therefore'be manually located in either oi its two active or in itsnonactive position. 1 5, .As previously stated the shaft 22 is pro- I videdatjts extreme'right end with a loner pih i o n ,26. LAThelatter is longl enough so that th el lateral displacement thereof does not effect the further mechanism and said 5.0Ldisplacementma)v therefore be overlooked. Always 'in mesh with said pinion 26 is the universal master gear 37, slidablyv and rotatahly mounted upon a shaft fastened in thefframework of the machine, best shown 5,5in11` ig. 8. Iheuniversal master gear is adapted to mesh with the -set of totalizer carrying,A gears 39 .rotatably mounted upon a shaft-40 each carrying gear 39 is in mesh with an intermediate idle `gear 4l, which in sturn vis in lmesh with the numeral `gear 42 A4which is provided with a set of numerals upon a cylindrical disk rigidly fastened thereto: Coperating with the carrying gears 39 arel asetof carriable 43: 6 5 .m0ufnted singly=-upon a set of supporting levers 44, which levers'are supportedxupon shafts mounted in the framework.

desired.

There will now be described the:mechannisrn by means of which both'the universal master gear 37, and the universal ,master dog are given their proper lateral location simultaneouslyand coperatingly. -The framework 55 is supported at its lower end by the rock` shaft 52 and at its upper-end lgr-f the stationary shaft 57. Rigidly fastened to said framework and extending therefrom tothe rightis a shaft .58 which is provided with rack teeth, 59, which mesh which is pivoted in the framing. `The shaft with a spur gear wheelO, rigidly fastened to the lower end of a vert-ical shaft 6L and Gl is provided at its .upper end with another spur gear wheel 62 of equa-lv size, an d the latter gear wheel meshes at itsvfront .with

wall ofv the columnar totalizer.

the operation of the machine wheneverv sion 65 upon which is mounted the master gear 37. It is thus evident that the universal master gear and the universal master dog have an equallateral movement. The

-parts are so shaped that both are brought into cooperation with their parts simultaneously.

The gear wheel 62 meshes at its back with another rack 66v (Fig.l 3), also slidably mounted in `the framing of the machine.

The rack is provided with a tension spring 67, which has one endA fastened to the rack and the other end lfastened to the framing. There is Athus produced a tendency to carry the latter rack, 66, to the right and therefore toA move the universal master gear and master dogconstantly tothe left. The'latter is their normal position.

Thefrack bar 66" is provided at its left with a stud 68,A whereonis p-ivotally mounted a hook'bar 69 (Figs. 3, 4fv and The latter is provided with a leaf spring 70 fastened thereto and whose end rests upon an exten'- sion 7:1' -of the rack bar 66 and the result of whiclris that the hook bar 69 normally as sumes.elevated'positionl The hook bar 69 is provided'with a hook 72 which is adapted to cooperate with an extension 73 formed upon the yback lower lcorner of the right During any totalizer provided with such an eX- tensionpasses over said hook 72 then the latter will be engaged by the former and as theI totalizer moves to the left the hook will be pulled along therewith. Therefore so will also the rack bar 66. Because of the mechanism above described, the result will be that there will also be pulled along, but to the right, and not to the left, both the universal master gear and universal master dog. The operating of the numeral key levers of the typewriter at this moment will therefore result in the operating of the proper sections of the universal totalizer.

'universal master mechanism automatically return to its normal position. Said normal position as above described corresponds to the highest decimal place location. In order to permit said automatic returningthe hook bar 69 is provided toward its middle on its lower edge with a disconnecting incline 7a. As the hook bar is pulled along to the left by any of the columnar totalizers, the incline 74 also travels to the left. Immediately after the units decimal location thereof the incline makes contact with the underside of a fixed disconnecting bracket, 75` fastened to the framing' of the calculating machine. The continued movement of the incline 7 4 therefore causes the hook bar 69 to move downwardly and to retract the hook 72 from the extension 73 of the columosi Armata-riti;

nar totalizer. Immediately thereupon the tension spring 67 becomes effective and returns all the parts operated thereby to their normal or highest placedpositions.

It has previously been mentionedv that the' universal totalizer can be placed inthree conditions by means ofl the handlell', inv

two of which it is active and in the third of which is nonactive. It Vwould` be super-y fluous as well a objectionable topermit the universal master mechanism to reciprocate on account of the travely of the carriage andcolumnar totalizer thereon, whenever said?- of the framing andAi having extending' therev l reaches into afslot 79 formedatf-tl-e'leftlower corner of'aplate-SO, slidably mounted! l' upon the framework by' means of twoiir clined slots 81 which embraceA two studs 82 fastened in the frame work.' The lever 77i' isy also provided with a spring 83- whichl tends continually to move the back endiof said lever toward the right. Because ofthe con-A 1 struction of the 'parts thi'sresults in atend-f ency to move the plate 80 always to itsele'- vated position. Formed in saidI plateSOisY a horizontal slot 84 with two enlarged openings, 85, one at each end of said slotl EX- tending through said slot is a pin 861fastened into the hook bar 69. The parts.V areA so dimensioned that when the plate 80v is'in, its elevated position, the pin 86 is sufficiently high so that the hook 72 is also sufficiently elevated to be encountered and engaged by any extension 73 upon any columnar-totalizer. But when the shaft 2 2 is shifted' to its nonactive position the plate 80 is thereby depressed. Therefore so is' also the pin 8 6 and also the hook 72. The hook will there;- fore be too low to be engaged by any columnar totalizer extension 73 which might pass over it.

It is evident that by the mechanism above described the operator has at its disposal practically two calculating machines, namely the columnar calculating machine and the universal calculating machine. These might l 45 totalizer nonactive.

4"Laet/glee would be supe'riuous to-have said .extension 7B vupon the' columnar 'totalizersas there wouldb'e'no .columna'rtotal desired." For this "case it has'been I found convenient to l replace the columnar totaliaer byl ajdummy total iaer, 90, as shown 'in'FigQfL The dummy totalizer contains no wheelsl but has means of iasteriing it to the' totalizer 'bar and jis provided with'ithe extension "73,' 'It isf/'evi- 4loident that the iordinary columnar ,totaliz'ers and 'the .dummy totalizlers l canrfbe' mounted together upon thetotalizerbar. svlrlowrkmany oi" each and. their arrangement lupon said bar will 'depend'u'pon 'the l "lforr'n'I required,

Eachfthes'e three :mentioned possibilities canVl be jbrougltabout by the manual adjustment'ofthe handleil But :55 in casev this formis predetenninedhas it sordinarily is'in commerciallho'uses the-manual adjustment i'sfthen 'inconvenient and an automatic mechanism is highly desirable. Such an vautomatic mechanism has been pro- 40 vid'edin thismachine. It consist-sofa three positions the cam 91' accompanyingl the columuar totaliaer is givenits .own proper level. In this partiCul'arcaSe the cam eX tends least downward when the roller is in its highest position, the carniextends more downward to cause thek roller :to assume its middle positioinfand theca'ni cxtlends'most downward to cause tl1e,'roller toassume its lowest position. v,The positioning'vof these ca ms over the roller therefore automatically locates the -roller in the "desired positions thereof and thus automatically brings the universal totalizer" in its various required conditions. A

It has. been Stated that the @am 91 is. asso- "ciated with the columnar totalizeri The actual construction of this association ls'immaterial.v What 1s necessary and suiiiclent is` that the totalizer cooperate with its mas "tcrlmechanisrn simultaneously 'with the cam" "cdperatingfivith the roller.: Purely yfor fconvenie'nce however-'the cam has been fastened 'tothe' totalizer. The placing of the `ftotalizer upon the totalizer bar in any f desired' positionl therefore simultaneously causes th fl'placing'oi' thevcarn in its required operative/position scribed in theaboveme'ntioned patents' there 'found infthe mastermechanism, 1, aj mas- I `terfy`vheel, Imaster. dog, 3, a" stationary' f'baifcoperating with theftotalizer carriable Jgear supporting' arms, AS, an' liner situated Y unimedi'ately, @to thel 'right of theMma-ster rivheel, and` 5, a stationary pointer to indi- "c'ate to thefope'rator: the particular decimal place of" operation yof the totalizer. It is of 'course understood that there are similar jniechanisms provided for theuniversal master mechanism. The yuniversal master mechanism 'therefore contains a moving master Imechanism whichis composed of, 1, a master wheel, 2,'fa master dog, 3, a bar coperatrrith' the .totalizer carriable gear sup- Eporting arms, 1, and a' liner ,situated imme- "diatel'y" to,` the right of the vmaster Wheel,`

and 5, a pointer to'indicate to the operator the .particular decimal place of operation of the totalizer` In' other machines .the master mechanism may, of course, contain elementsy l differing more or lessfrom those enumerated. The totality of parts associated with the master wheel may be called .the master group. It may therefore be. said that the machine is provided with a stationary masterv group and also with a ,reciprocating master group.

ln my pending application Sr. No. 629,308, filed May i3., 1911, there is shown a disconnect handle for preventing the operation o fl t'he rifiaster 'wheel by the lieys, and when thisliandle is moved to disconnecting position it also renders inoperative the means Vfor connecting the. totalizcr intermittently with the carriage.
